ANIMAL TISSUE
INTRODUCTION
On the basis of the function and occurrence ,tissues present in animal body is called animal tissue. These
animal tissue is classified into the following four types:
 Epithelial tissue
 Connective tissue
 Muscular tissue
 Nervous tissue
EPITHELIAL TISSUE ANIMAL TISSUE:
 The covering or protective tissues in animal body is epithelial tissue
 It is the simplest protective tissue.
 It forms a barrier to keep different body systems separated from each other.
FUNCTIONS:
It protects the underlying cells from drying, injury, infections and also from harmful effects of chemicals.
 It plays an important role in coordination of body and environment by interchanging various substances
in all body parts.
 It helps in absorption if water and nutrients and in diffusion of gases.
 It helps in elimination of waste products from the body.
TYPES OF EPITHELIAL TISSUE

EPITHELIAL
TISSUE
CHARACTERISTICS LOCATION FUNCTION DIAGRAM
Simple
squamous
epithelium
· Single layered
· Closely fitted
· Very thin
§ Delicate lining
of blood vessels
§ Lung alveoli
Covering and
protection
Stratified
squamous
epithelium
Arranged in many layers
Outer side of the
skin
Prevents from
wearing and
tearing.
Cuboidal
epithelium
Cube shaped cells with
round nuclei
§ Lining of
kidney tubule.
Absorption,
excretion and
secretion.

2. § Ducts of
salivary glands
Columnar
epithelium
Pillar like cells with
elongated nuclei
Inner lining of
intestine
Absorption and
secretion
Ciliated
columnar
epithelium
Columnar cells with cilia.
§ Respiratory
tract
§ Oviducts
§ Spermducts.
Movement of cilia
pushes substance
like egg, sperm,
mucus forward.
Glandular
epithelium
Folding of epithelial
tissue. forms multi
cellular gland.
Gland of various
organs.
Those gland cells
secrete
substances.
CONNECTIVE TISSUE IN ANIMAL TISSUE
NAME OF THE
CONNECTIVE
TISSUE
CHARACTERISTICS & FUNCTION DIAGRAM
Blood
RBCs transport oxygen and carbon di oxide; WBCs fight
with diseases by producing antibodies; BLOOD
PLATELETs help in clotting of blood.
Bones
Very strong, non-flexible, porous, hard, rigid, rich
in calcium and phosphorus. It forms the framework that
supports the body.
Cartilages
Specialized tissue having widely spaced cells. Matrix is
composed of protein and sugars. It provides smoothness
to the bone surfaces at the joint.
Areolar tissue
The tissue is found between the organs. It supports the
organs by filling. It also provides support to the internal
organ. It repairs the tissues.
Adipose tissue
It serves as a fat reservoir, keep visceral organs in
position.
Ligament The fibre connect bone to another bone.
Tendon These connect muscles to bone.

NERVOUS TISSUE IN ANIMAL TISSUE:
DESCRIPTION DIAGRAM
· It receives stimulus and transmits it from one part of tissue to other.
· These are highly spcialized for receiving stimulus and rapid transmission
from one region to another.
· Nervous tissues in animal tissue are present in brain, Spinal cord and all
type of nerves.
· Cell body consists of cytoplasm, nucleus and cell membrane
· Axon is a single long conducting fibre extending from neuron.
· Dendrites are short branched fibres of neuron which receive nerve
impulse.
QUESTIONS RELATED TO ANIMAL TISSUE:
Qns1 Name the type of epithelium present in respiratory tract. What is its specialization?
Ans1 Ciliated columnar epithelium in animal tissue is present in the respiratory tract of human. It
has specialized hair-like projection called cilia which help in the movement of substances and mucus
forward.
Qs2 Give three differences between epithelial tissue and connective tissue.
Ans2 Differences between epithelial and connective tissues are
KEY POINTS EPITHELIAL TISSUE CONNECTIVE TISSUU
Arrangement Cells are tightly packed These cells are loosely packed
Inter cellular
substances
All cells contain very little or no
intercellular matrix
Space between cells is filled with
non-living matrix (solid or fluid)
Function
It is the covering tissue and
protects body from infections,
injury etc.
The cell is the connecting tissue as
it connects various body organs.
Qs3 Which tissue makes the bones smooth at joint surface.
Ans3 Cartilage is the tissue that smoothens bones surface at joints.

4. Qs4 Where do you find the cartilage in animal tissue?
Ans4 Cartilage is present in nose, trachea, ear and larynx.
Qs5 What happens when blood platelets are removed from blood?
Ans5 If the blood platelets are removed from the body then blood clotting will not occur at the site of
injury. Bleeding will continue and a significant loss of blood may lead to death.
Qs6 Write the function of areolar tissue in animal tissue.
Ans6 Areolar tissue fill the space inside the organs and supports internal organs of the body. They
also help in repair of tissues.
Qs7 Name the tissue by identified by their functions.
 Connects bone to bone
 Forms inner lining of alveoli
 Having chondrocytes as cells
 Transporting stimulus
Ans7 The tissues are
 Ligament
 Simple squamous epithelium
 Cartilage

Qs8 Name the tissue in animal tissue responsible for our movement.
Ans8 Muscular tissue is responsible for our locomotion and movement.
Qs9 Name the tissue associated to these functions?
 Flat tissue which is present in the inner buccal cavity
 T hose tissue that forms connects muscle to bone in humans
 Tissue that transports food in plants
 Connective tissue with fluid matrix
 Tissue that present in the brain
Ans9 The proper tissues are
 Squamous epithelium
 Tendons
 Phloem
 Adipose tissue
 Blood
 Nervous tissue
Qs10 Mention the features of cardiac tissue.
Ans10 features of cardiac muscular tissue in animal tissue are
 These are involuntary muscle
 Cells of these muscles are cylindrical, branched and uni -nucleate.

5.  These muscles show rhythmic contraction and relaxation throughout the life.
